Scalar form factors in SU(3) chiral perturbation theory

Abstract
The scalar form factors for the pions and kaons are calculated in SU(3) Chiral Perturbation Theory at order p(6), in the isospin limit m(u)=m(d)=(m) over cap. We find in general sizable corrections of O(p(6)). We use our results to obtain information on the 1/N-c suppressed low energy constants L-4(r) and L-6(r) as well as on two O(p(6)) low energy constants. We present some numerical results for masses and decay constants as well. We derive a relation for the scalar form factors analogous to Sirlin's relation for vector form factors.
